DAVID A. BRAWLEY AND JAMES FRANK LEWIS, OF CHARLESTON, \VEST VIRGINIA.

AUTOMATIC WEATHER- STRIP.

SPECIFICATION forming part of Letters Patent No. 591,809, dated October 19, 1897.

I Application filed March 3, 1897. Serial No. 625,905. (No model.) I

To all whom it may concern.-

Be it known that we, DAVID A. BRAWLEY and JAMES FRANK Lnvvrs, citizens of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Automatic Weather-Strips for Doors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has relation to improvements in automatic weather-strips; and the object is to provide a simple and elfective automatic device for closing the-space between the bottom of the door and the door-sill.

To this end the novelty consists in the construction, combination, and arrangement of the several parts of the same, as will be here.- inafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference-characters indicate the same parts of the invention.

Figure 1 is a front elevation of the sill and lower end of an outside door, showing our improved automatic weatherstrip in place. Fig. 2 is a similar view showing the. door partly open. section through the operating-bolt. Fig. 4 is a top plan view of the same; and Fig. 5 is a transverse section of the lower end of the door.

1 represents an ordinary outside door, hinged in the usual manner to the frame 2 and opening inwardly, and 3 represents the door-sill. The lower end of the door is provided with a longitudinal rectangular groove 4, extending the entire width of said door.

5 represents a metal plate secured to the rear vertical edge 6 of the door, and it is formed with an integral horizontal cylindrical guide-sleeve 7, which receives the cylindrical end S of the longitudinal approximately rectangular bar 9,the forward rectangular end 10 of which extends through the correspondingly-shaped guide-orifice 12 in the plate 13, secured to the front edge 14 of the door.

15 represents a spiral spring encompassing the guide-sleeve 7 and the projecting portion the upper edge of the follower.

Fig. 3 is a vertical longitudinal of the cylindrical end 8 of the bar 9, the outer end of said spring resting against the inner face of the plate 5 and its inner end abutting against a collar 16 on the shoulder 17 of the bar 9.

18 represents a follower, rectangular in cross-section, and snugly fitting the lower end of the groove 4 and extending its entire length. This follower 18 is provided with two sets of vertical parallel cars 19 1 9, connected at their upper ends by a transverse bolt 20, which extends across the upper edgeof the bar 9, which supports the follower in position. The bar 9 is turned downwardly out of its horizontal plane and then back again, at two points, to form the transverse notches 21 21, each of which is formed with an inclined face 22 on the side contiguous to the bolts 20, which support the follower. The doWnardly-extending portions 23 23 of the bolt, which form the notches, project into recesses24 21, formed in One of the side walls of these recesses forms an inclined plane 25, which abuts against the contiguous inclined face 26 of the bent portion 23 of the bar 9, so that when the projecting end 10 of the bar is forced horizontally inward its inclined faces 26 26, coming in contact with the inclined walls 25 of the follower, force the latter vertically downward, and when the pressure is released from the end 10 the spiral spring 15 presses it outward again, and the inclined faces 22 22 of the bar, riding under the transverse bolts 20 20, raises the follower vertically within its groove 4, and thus restores it to its normal posit-ion. The outer end 10 of the bar 9 is formed with a beveled face 27, terminating in a rounded vertical edge 28.

29 represents a horizontal groove in the face of the door-frame contiguous to the outer edge of the door and in the same horizontal plane with the projecting end 10 of the bar 9, and the forward end 30 of this groove is beveled outwardly to correspond to the beveled face 27 of the bar 9. WVhen the door is open, the end of the bar 9 projects as shown, and the follower 18 is Withdrawn into the groove 4, its lower edge flush with the lower edge of the door, and when the door is closed the end 10 of the bar 9 engages the beveled end 30 of the groove 29, which forces the bar 9 inwardly and presses the lower edge of the follower into intimate contact with the upper face of the door-sill, thereby making awind, rain, snow, and storm proof joint. In practice a strip of rubber or suitable flexible material may be secured to the lower edge of the follower to increase its efficiency and although we have specifically described the construction and relative arrangement of the several elements of our invention we do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of our invention without departing from the spirit thereof.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

An automatic weather-strip, comprising a hinged door and its frame, the lower edge of said door being formed with a longitudinal rectangular groove 4, a plate 5 provided with an integral cylindrical guide-sleeve 7, and the oppositely-disposed guide-plate 13 provided with a rectangular orifice 12, an approximately rectangular bar 9 formed with a cylindrical end 8 engaging the guide-sleeve 7, its

opposite rectangular beveled end 10 projectlar follower 18 mounted in said groove 4 and extending parallel with and below said bar, and provided with the vertical parallel cars 19, 19 connected at their upper ends by a transverse bolt 20 extending across the upper edge of the bar 9, the upper edge of saidfollower being formed with the recesses 24, each of which has an inclined wall 25, and are adapted to receive the bent portions 23 of said bar 9, substantially as and for the purpose set forth.

In testimony whereof we aifix our signatures in presence of two witnesses.
